When you transpire to be learning to pass the BCMSN evaluation on the way to earning your CCNP accreditation, you are heading to incorporate to your CCNA knowledgebase each person action of the procedure. Nowhere is that https://youtu.be/Qe6Gf0du8Zs?si=2xyxd7RqEXgF_Ldh than configuring a trunk in amongst two switches.
You have an being familiar with of that IEEE 802.1 Q (" dot1q") and ISL are your two possibilities of trunking methods, and you know the principal distinctions regarding the two. Exactly what you could not have comprehended is that you can locate a 3rd trunking therapy that is working in in amongst your Cisco switches, and while it can be a clear procedure to numerous, you had substantially improved know about it for your BCMSN and other CCNP examinations!
The Cisco-proprietary Dynamic Trunking Protocol (DTP) actively tends to make an endeavor to operate out a trunk connection with the distant swap. This seems fantastic, however there is a charge in overhead - DTP frames are transmitted each single thirty seconds. If you make your mind up to set up a port as a non-negotiable trunk port, there is no will need to have for the port to ship DTP frames.
DTP can be turned off at the shopper interface stage with the switchport nonegotiate command, but as you see beneath, you can not remodel DTP off up correct up until the port is not in dynamic desirable trunking manner. (Dynamic preferable is the default method for the bulk of Cisco switch ports.).
SW2( config) #int rapidly /eight.
SW2( config-if) #switchport nonegotiate.
Command turned down: Conflict in in in between 'nonegotiate' and 'lively' place.
SW2( config-if) #switchport process?
accessibility Recognized trunking technique to Accessibility unconditionally.
dynamic Established trunking method to dynamically negotiate accessibility or trunk method.
trunk Set trunking strategy to TRUNK unconditionally.
SW2( config-if) #switchport strategy trunk.
SW2( config-if) #switchport nonegotiate.
When you happen to be working with Cisco switches in a home laboratory or rack rental natural natural environment, run IOS Enable on a frequent foundation to see what possibilities are speedily available for the instructions you are training with. Cisco change ports have quite a number of solutions, and the extremely greatest way to obtain them is with a single easy image - the query mark!
